A method to estimate the size of single-chain nanoparticles under severe crowding conditions
Asenjo Sanz, Isabel; Verde Sesto, Ester; Pomposo Alonso, José Adolfo (Royal Society of Chemistry, 2022-01-05)[EN] Single-chain nanoparticles (SCNPs) result from the folding of isolated polymer chains via intramolecular interactions. Currently, there is no theory able to rationalize the astonishing conformational behaviour of SCNPs ... -
Advances in the Multi-Orthogonal Folding of Single Polymer Chains into Single-Chain Nanoparticles
Blázquez Martín, Agustín; Verde Sesto, Ester; Moreno Segurado, Angel José; Arbe Méndez, María Aranzazu; Colmenero de León, Juan ; Pomposo Alonso, José Adolfo (MDPI, 2021-01-18)The folding of certain proteins (e.g., enzymes) into perfectly defined 3D conformations via multi-orthogonal interactions is critical to their function. Concerning synthetic polymers chains, the “folding” of individual ... -
Advances in the Phototriggered Synthesis of Single-Chain Polymer Nanoparticles
Clean use of photons from light to activate chemical reactions offers many possibilities in different fields, from chemistry and biology to materials science and medicine. This review article describes the advances carried ... -
Collective Motions and Mechanical Response of a Bulk of Single-Chain Nano-Particles Synthesized by Click-Chemistry
Maiz, Jon; Verde Sesto, Ester; Asenjo Sanz, Isabel; Fouquet, Peter; Porcar, Lionel; Pomposo Alonso, José Adolfo ; Malo de Molina, Paula; Arbe Méndez, María Aranzazu; Colmenero de León, Juan (MDPI, 2020-12-25)We investigate the effect of intra-molecular cross-links on the properties of polymer bulks. To do this, we apply a combination of thermal, rheological, diffraction, and neutron spin echo experiments covering the inter-molecular ... -
Disentangling Component Dynamics in an All-Polymer Nanocomposite Based on Single-Chain Nanoparticles by Quasielastic Neutron Scattering
Maiz, Jon; Verde Sesto, Ester; Asenjo Sanz, Isabel; Mangin-Thro, Lucile; Frick, Bernhard; Pomposo Alonso, José Adolfo ; Arbe Méndez, María Aranzazu; Colmenero de León, Juan (American Chemical Society, 2022-02)[EN] We have investigated an all-polymer nanocomposite (NC) consisting of single-chain nanoparticles (SCNPs) immersed in a matrix of linear chains of their precursors (25/75% composition in weight). The SCNPs were previously ... -
Dynamic Processes and Mechanisms Involved in Relaxations of Single-Chain Nano-Particle Melts
Maiz, Jon; Verde Sesto, Ester; Asenjo Sanz, Isabel; Malo de Molina, Paula; Frick, Bernhard; Pomposo Alonso, José Adolfo ; Arbe Méndez, María Aranzazu; Colmenero de León, Juan (MDPI, 2021-07-14)We present a combined study by quasielastic neutron scattering (QENS), dielectric and mechanical spectroscopy, calorimetry and wide-angle X-ray diffraction on single-chain nano-particles (SCNPs), using the corresponding ... -
Gold Nanoclusters Synthesized within Single-Chain Nanoparticles as Catalytic Nanoreactors in Water
Pinacho Olaciregui, Jokin; Verde Sesto, Ester; Taton, Daniel; Pomposo Alonso, José Adolfo (MDPI, 2024-01-30)Metalloenzymes are able to catalyze complex biochemical reactions in cellular (aqueous) media with high efficiency. In recent years, a variety of metal-containing single-chain nanoparticles (SCNPs) have been synthesized ... -
Metamorphosis of a Commodity Plastic like PVC to Efficient Catalytic Single-Chain Nanoparticles
Blázquez Martín, Agustín; Verde Sesto, Ester; Arbe Méndez, María Aranzazu; Pomposo Alonso, José Adolfo (Wiley, 2023-11)We perform the conversion of a commodity plastic of common use in pipes, window frames, medical devices, flexible hoses, etc. like polyvinyl chloride (PVC) to single-chain nanoparticles (SCNPs). SCNPs are versatile, ... -
New poly(ionic liquid)s based on poly(azomethine-pyridinium) salts and its use as heterogeneous catalysts for CO2 conversion
Maya, Eva M.; Verde Sesto, Ester; Mantione, Daniele; Iglesias, Marta; Mecerreyes Molero, David (Elsevier, 2018-07-21)A fast and simple synthetic route towards a new family of poly(ionic liquids) based on aromatic crosslinked poly(azomethine-pyridinium) salts is described. These new polymers were prepared in one step from new diamine ... -
Stars, combs and bottlebrushes of elastic single-chain nanoparticles
Hierarchical self-assembly of structural elements gives rise to superstructures often with outstanding properties when compared to individual elements, as first observed in nature. While folding of individual synthetic ... -
Toward Long-Term-Dispersible, Metal-Free Single-Chain Nanoparticles
Blázquez Martín, Agustín; Ruiz Bardillo, Ainara; Verde Sesto, Ester; Iturrospe Ibarra, Amaia; Arbe Méndez, María Aranzazu; Pomposo Alonso, José Adolfo (MDPI, 2023-04-18)We report herein on a new platform for synthesizing stable, inert, and dispersible metal-free single-chain nanoparticles (SCNPs) via intramolecular metal-traceless azide–alkyne click chemistry. It is well known that SCNPs ...
